BFGoodrich All-Terrain T/A KO2

They did well with the recent snow.

3/5

BFGoodrich All-Terrain T/A KO2

Great for gravel and rocky terrain but not as effective on wet tarmac. I have fitted them to my L200, and I have to engage all-wheel drive on rainy days as the back of the pickup tends to slide. In the snow they are alright, but in icy conditions they are terrible, however, they are good in muddy conditions.

5/5

BFGoodrich All-Terrain T/A KO2

The tyres provide good grip and last a long time. They look great and are off-road superb.

Tyres that are superb in all conditions.

285/55 R20 is suitable for SUVs and pick-ups as they are larger diameter tyres. Tyres of this size have a large sidewall which protects the wheel on rougher roads. This size is easy to break down. 285 is the width in mm. 55 is the aspect ratio where the sidewall height is 55% of 285mm, which is 157mm. R 20 means it is a radial tyre, a tyre where the cords radiate from the centre of the tyre, and that it is on a 20-inch rim. This gives it an overall diameter of 822mm. That sidewall protects your wheel. We supply 285/55 R20 at Tyres.co.uk.
